    Running Win 7 64 bit on X58 with Sapphire 5770 oc'd to 960/1350, and using the latest Afterburner (v2.0.0).

    It appears that in both, Afterburner and ATI Overdrive, the max core clock speed I can set it to is 960, yet some folks mention they were able to set it over 1000 and keep stable.

    My questions:
    • How can I set the core clock to above the apparent ceiling of 960?
    • How do I enable voltage modification (currently locked in Overdrive & Afterburner)?
    • Your recommendations for higher (>950/1350) stable OC settings will be highly appreciated ...

    Using stock gpu cooler with modified fan speed profile. Under heavy load - 100% fan rpm are utilized keeping temps to ~80 steady. the case i am using - Sniper - has great air flow.
